Question

Only the last two questions 

(2) Yellowstone National Park is one the most traveled geologic sites in the world. Visitors from all over come to see the park's star "Old Faithful" geyser erupt every 90 minutes or so. Yellowstone, however, is also one of the most dangerous geologic sites in the world. It is known as a supervolcano, with a magma chamber 1000x greater than any other mapped North in the world. It is estimated that Yellowstone erupts violently every 600,000 years on average (not including smaller lava flows.) The last large explosive eruption happened 640,000 years ago. 250 200 150 Wisdom, MT 100 Montana 50 Yellowstone Natl.

Expert Solution
Step 1: Introduction

The image in the question shows a 3D model of Yellowstone supervolcano. There is some scale which shows the areal extension and depth of the mantle plume beneath the surface.
